New PSU and No Joy

[Shredder]

Hi,
I just installed a PSU that will support the 3870 x 2 video card with the proper PCIe2 8 pin and 6 pin power connections and now I am stuck using default bios settings and locking up on anything that uses 3d.

Problem 1 :
Vid card ran fine but locked on 2 x 6 pin PCIE, COD4 ran great too. Now its unlocked, default clocks and keeps locking up on 3dmark and cod4, to the point that a hard reboot is required. I have installed latest ati drivers but rolled them back 1 level after nothing changed.

Problem 2 :
The Bios. The Asus Blitz edition like many boards allows change of settings, save and exit then the machine shuts down, reboots and your new settings are applied.
With this PSU it shuts down and when the reboot sequence starts it pulses power for a second and then shuts down, refuses to fire up until I press clear bios reset. This keeps me running only default settings, LAME.
Frustrated.

PSU
ToughPower ATX 12v 2.2 and ESP 12v 2.91 1200w

Mobo
Asus Blitz Edition

Video Card
ATI 3870 x 2

Fixed problem 1 by removing all ATI software , then reinstalling latest drivers and reinstalling COD4

Did you remember to bump up all of the required voltages after the first time it did it? (i.e. ram voltages?)

Other than that... all I can think of is to ensure that your PSU connections are properly inserted.

Still nothing, it requires a 30 sec shut down before restarting, even with PSU unplugged it feeds power to the board after shut off.

Hmmm, I have a toughpower 850, but its never powered a full system yet.
I have tested it with fans, controllers and lights, and it did NOT like the CCFL’s
or one of my fan controllers. The one thing these two devices had in common
was they both use an internal charge pump power supply (+5 to +15), these can be noisy as they can
draw high frequency current spikes.
I figured the noise triggered the toughpower’s protection circuits and shutdown.
Maybe if the psu was fully loaded it wouldn’t happen, but I fixed it by putting them
on a small external power supply. um, ya, a wall adapter!

anyways, to wrap this up, remove any of that kind of stuff and try it.

I dont have any Lights or fan controllers attached to the psu. Mobo, water pump, hard drives, fans ,dvd drive nothing out of the ordinary. This build has ran for a year with the 700 PSU. I was able to bump the clock up using AI Suite (Asus Tweak Software)

Never use software.

Make sure in your bios your voltages are properly setup for your cpu, nb, AND memory.

If I could use bios, I would not have made the post :( , at present software is my only option. Asus suggests I remove the motherboard from the case and fire it up on an inslated table....This board worked fine as installed for months with the 700 watt psu, I really dont think I have a grounding issue with the board as installed.

Local supplier stepped up to the plate and tossed me a second 1200 watt , it worked great as soon as it was installed. They were going to attempt a return on the product to Thermaltake.
Thanks for your ideas and input folks.
